v To all whom itma concern:

Be it known that LTnnononn H. Limnn,

a citizen of the United. States, and a resident the following is a full, clear, and exactdescription thereof, reference being. had to the accompanying drawings, and to the letters of reference marked thereon, which form' a part of this specification. v This inventionrelates to improvements in .music desk hangers or hinges for upright. pianos, and the-invention consists in the matters hereinafter set forth and more particularly pointed outin the appendedclalms,

' provide a music desk hanger or hinge for 20' Among the objects of my inventionfislto pianos which is so constructed and arranged as to perm-it the music desk to be swung for-' I Q .wardly and upwardly at its lower side, for the purpose of exposing the thereoffor i-ns ency of the des slh ding inwardly toward the iilano action in rearection, w 1e avoiding tendpiano action in a manner to injure the mechanism of the action", and also 'to provide a' hanger for this purpose which is so constructedwith respect to the hjngepinztherefor as to avoid loosenessof the parts "and conse In the drawings zF-igure l is 'a vertical section -of the -11 per part of the casing of an upright piano, s owing the music desk and a hanger therefor embod my invention. Fig. 2' is a generally simi ar fragmentary view showing the music desk swung'lup wardly to apositionto'expose the piano ac -tion in rear of the same.- Fig. 3 '18 a fragmentary section,- taken on line 31 -3 of Fig. 1. Fig. 4 is aperspective view of one of the hangers.

Fig. 5 1s a viewfisimilar to'Fig.

.As shown in the drawings, A designates," as

a Whole, the upper" ortion of the casing of an gupright piano,','an B- designates a swinging muslcdesk of usual form which constltutes the front'wall of said upper portion of the casing, it being swingingly mounted at its u er side in the casing so that it may be swung orwardly and upwardly to expose the piano action for inspection thereof, or'to such angle as to afford an inclined music desk-to su port the music. Said music desk B is herein shown' as supported between and mounted on posts or pilasteis A constituting parts of the piano .casing. The desk is supported which engage hinge. pins or studs wfixed to the upper ends of said posts A Two of said.

from said posts or 'pilasters by hangers C hangers and two pins or studsare employed,

one pair located at each end of the up er'side of the desk, in the usual manner.

he said hangers each embraces a sh ank portion a by which it is attachedto the rear 'face' of the music desk, as by means of screws extending through apertures 12 thereof: The hanger is formed at its other end'to provide a hook oropen loop, designated 'a a whole by '0 Said hook comprises two si e members 0 c r and is open at its lower and closed at its upper end; It-is adapted to hook over the hinge pinor stud win a manner to swi-ngingly and removablysupport the desk in the casing. The u per or closed end of said hook is formed Wit an outwardly offset ortion c which provides on the inner faoeo the outer member c of the hook an oblique stop shoul-l der-or surface of which engages the hinge pin or stud a in amanner to avoid the tendency .of the music desk being pushedinwardly toward the piano action when the desk isswung' I to the position shown in Fig. 2 or to fall 1n- Wardly by'gravity when swungupward beyond -the horizontal.

The; free end-ofthe inner member c. of the hook is curved away from the member c"; as indicated at 0 to provide a flaring receiving opening of the hook or loop, which facilitates the application of the hanger to the supporting pin or stud-a.

" Inorder that the hanger, as a whole nay be applied to the inner face of the music desk generally parallel with theplene of said inner face thereof, while avoiding the ofiset portion 0 of the hanger, the shank c is, offset from the-outer member a of the loop or hook to the plane of the offset portion c,.it being joined to said! outer mernber;v by an offset portion a, as indicated 1-n Fig. 4/

" It will thus be seen thazt'the hangers C C serve in the ordinaiynner to swingingly wardly' at an angle to afford a music desk of the proper inclination, and that when said music-desk occupies its upper or open posinecessity of recessing the desk to receive the gaged ,tion the engagement of the shoulders c with the pins serves to prevent the desk falling inwardly by ravity or being accidentally pushed inwai dly into contact with the mechanism of the piano action, as would occur if the hanger loops or hooks be'made straight throughout their length. The said hanger pins or studs a are herein shown as rovided with heads a 'acing conical, shoulders a which are enby the edges of the hook members when the desk is mounted in position. This form of hanger stud or pin enables the music desk to be accurately adjusted laterally, or centered in the casing, while at the same time avoiding an undue binding or chafing of the hangers against saidpins or studs, or the desk against the pilasters.

The spread of the hooks or loops 0 may be made slightly narrower at the extremities of their closed ends than the diameter of the hinge pins or-studs, as shown in Fig. 5, whereby each of said pins or studs finds its bearing at two points on the opposite sides of the hook instead of bearing against the inner curved'face at the extreme end of the 'hook. An advantage of the arrangement shown is that it avoids looseness of fit between the hanger and pin and thereby prevents the parts rattling one on the other. If desired the-bearing Cportion of the pins or studs may be covere by bushings made of cushioning material, such as felt, rubber and the like.

It is apparent that I have provided an ex- I ceedingly simple and effective hanger for the thereof, of hangers for swingingly supportabove set forth.

purpose described, having the advantages Said hangers may advantageously be madeof a single piece of bar or strap metal which is properly bent or shaped tovproduce the offset hook or loop described, but may be otherwise constructed. The specific form of the hanger may be varied, however, so long as the stop is preserved at the hinged portion of the hanger which avoids tendency of inward shifting of the raised oropen desk.

I claim as my invention 1. The combination with the casing of an upright piano and the swinging music desk thereof, ,ofhangersfor swingingly supporting the music desk in the casing, combined with pins or;studs in the casing detachably engaged by said hangers, said hangers-being formed on their inner sides adjacent to the desk with interior stop surfaces or shoulders adapted for engagement by the said pins or studs when the desk is swung upwardly in a manner tqavoid tendency of the desk being shifted rearwardly relatively to said pins or studs.

2. The combination with the casing of an upright piano and the swingingmusic desk having outwardly ing said music desk'in the casing, ooznbhied with pins in said casing detachably engaged by the hangers, said hangers comprising shank portions attached to the rear face of the music desk, and hooks engaging thepins which are open at their lower ends and closed at their up 'ier ends, the upper or closed ends of said iooks being o'i'fset, ior'the purpose set forth.

3. The combination with the casing of an upright piano and the swinging music desk thereof, of hangers for swingingly supporting said music desk in the casing, combined withpins in said casing detachably engaged by the hangers, said h angers comprising sh ank portions attached to the rear l' ace of theniusic desk, and hooks engaging the pins which are open at theirlower ends and closed at their upper ends, the upper or closed ends of said andppen at their lower ends and closed at their upper ends, the spread of said hooks being of less width at their upper orclosed ends than the diameter of the pins, whereby said pins engage with the inner faces of the side members only of the hooks below said closed ends, for the purposes st forth.

5. hanger for music desks and-the like comprising the shank c, the hook or loop portion having the offset portion 0 to provide a stop surface or shoulder c as and for the purpose set forth. I

6. The combination with the casing of an upright piano and the swinging niusic 'desk thereof, of hangers for swingingly supporting said music desk in the casing, combined with pins in said casing detachably engaged by the hangers, said hangers embracing elongated loops or hooks through which said pins extend, andthe pins being provided nat their inner ends with heads having outwardly facing con cal shoulders adapted to engage the laterally 1111161 sides of the hanger 120 hooks or loops, for the purpose set forth.

In testimony, that I claim the foregoing as my invention I affix my signature in the presence of two witnesses, this 4th day of June A. D. 1908.
